[o n/Z 'lu/mm, it 71u17/ concern:

Be it known that I, HERMANN SGHUBERTH, a subject of the German Emperor, residing at Gera, Reuss, in the German Empire, have invented certain new and useful Improvements in Profiling-Machines, of which the Jfollowing is a specification.

The object of this invention is a device for working articles with curved profiles on turninglathes, shaping machines, millingmachines, grooving or paring machines,and other machine-tools. Such devices as have become known up to the present could only be used to produce either several simple profiles, in which case the tool advances very irregularly, or only a single more complex proile. My device, on the contrary, possesses the great advantage that an indefinite number of protiles may thereby be produced, however sudden and complex or sinuous their curves may be, while the tool advances at very nearly the same rate.

In order that this invention may be the better understood, I now proceed to describe the same, reference being' had to the accompanying drawings and to the ligures marked thereon.

Figures l and 2 are part sectional views in elevation and plan of a form of construction of the mechanism Jfor operating the guidingpin. Fig'. 3 is a i'ront elevation, partly in section, of a lathe provided with one form of construction of the present invention. Fig. 4 shows partly a side elevation, partly a vertical section, seen against Fig. 3 from the left. Fig. is a front elevation of a milling-machine constructed according to the present invention. Fig. 6 is the central vertical section through Fig. 5 seen from the left. Fig. 7 is an elevation of a vertically-arranged machine. Figs. 8 and 9 are vertical cross-sections oi' the lower part of Fig. 7. Fig. 10 is partly an elevation, partly a vertical section, showing a modified construction of the milling-machine shown by Figs. 7 to 9.

A guide-pin 3 is rigidly connected to an axle 1 and a cog-wheel 2. i/Vhen the axle 1 is rotated by any suitable means, the pin 3 slides in the guiding-groove cut into the templet 4, according to the successive engagement of the cog-wheel 2 with the pins 5 to 16. The row of pins 5 to 16, which has the function of a rack, renders it possible that the pin 3 traverses with ease the sharp pitch ot' the curve of the guiding-groove, because the corresponding tooth oi' the wheel 2 bears against the pin 9, &c., and causes a lever action, whereby the pin 3 is moved along the sharp curve.

Figs. 3 and 4 illustrate the device shown in Figs. 1 and 2 applied to a Wheel-lathe with double tool supports. A longitudinallygrooved axle 17 is operated by chain alternating mechanism or by other known means. This motion is transmitted by a worm 18 and a worm-wheel 19, engaging therewith, to a longitudinally-grooved axle 2U, on which is situated a bevel-wheel 2l, keyed thereto by a feather-key. The bevel-wheel 2l engages with a second bevel-wheel 22, connected to the slide 24 by the vertical axle 1. Therefore when the axle 17 is rotated the axle l is also rotated. The slide 24 is adapted to move on a second slide 23 in a plane parallel to it andv in any direction, (see Fig. 4,) the slide 23 being adapted to move on a base-plate 29, tixed or adjustable by hand only in a longitudinal direction thereto. To the plate 29 is fixed Ithe templet 4, inthe guiding-groove ot' which moves the end 3 ot' the axle l, serving as guiding-pin, the cog-wheel 2, rigidly connected to the axle 1, engaging successively with pins 5 to 16, Figs. 1 and 2, situated on the templet 4. The slide 24 follows the movement of the guiding-pin 3, because it is adapted to slide on the slide 23, and thelatter is adapted to move at right angles to the direction of the movement of the slide 24. A tool 27, fixed to the upper part 25 ot' the slide 24, is thus caused to make a movement corresponding to that of the guide-pin 3, and thus produces articles of. corresponding' shape. To obtain, this movement, it is therefore only necessary to give the templet 4 the form or' the article to be reproduced. 1f the slide 24 is pressed constantly in one direction by a spring 28 or other means in such a manner that the guide-pin 3 bears only against one side of the guiding-path provided on the templet 4, the other side of the guiding-path may be omitted.

The application of the mechanism described permits of kinematic reversal by using the templet 4 instead oi' the guide-pin 3 to produce the desired operative movement. For this purpose it suffices to arrest the slide 24 to put the whole support upside down and to provide the plate 29, which then becomes uppermost with the tool. 1n this case the plate 29 follows the movement of the templet 4 by means of the guiding-grooves, which may be in any direction, andthe production of the IOO IOS

IIO

article to be manufactured is also effected in the desired form.

The shaping-machine shown in Figs. 5 and 6 illustrates the transmission of the movement of the guide-pin to the tool and the piece of work under ope ation. An axle 31 is rotated by a stepped pulley. The rotation of the axle 31 is transmitted bya belt-pulley 32 and a half-twisted belt to the pulley 33 and by the latter to the adjustable shaping-spindle 34, which carries the shaiiing-tool 35. The axle 31 operates also a pair of bevel-wheels 36 37 and by means thereofl an axle 38, which operates the grooved axle 41 by a worm 39 and worm-wheel 40. rlhe axle 41 transmits its rotation by a worm 42 and a worm-wheel 43 to the vertical guide-axle 1, on which are situated the parts shown in Figs. 1 and 2, the cog-wheel 2, and guide-pin 3. r1`he templet 4, in the groove of which the guide-pin fixed to the end of the axle 1 is adapted to move, is rigidly connected to the work-table 47, adapted to slide on the rails 49, the slide 45, designed to support the guide-pin axle 1, being adapted to move on the transverse piece 48 of the machine. rlhe slide 45 is connected by a screw 46 with a slide 44, designed to support the shaping-tool or is adapted to ne rigidly adjustable relatively thereto. Therefore the rotation of the axle 31 causes both the rotation of the shaping-spindle 34, as also of the vertical axle 1 of the guide-pin 3. lVhen the latter slides, hereinbefore described, in the groove provided in the templet 4, this movement is taken up in the one direction by the slides 44 and 45, which are connected to each other, and in the other direction by the table 47, the result being a movement of the shaping-tool 35 along the piece to be made, which is held on the table 47, and this movement corresponds exactly to that determined by the shape of the templet 4. When the table 47 is immovable and the transverse piece 43 is adapted to move, the shaping device can execute both working movements in similar manner as in the case of the wheel-lathe illustrated in Figs. 3 and 4, and when a second slide is arranged adapted to slide perpendicularly to the direction of motion of the table 47 the movable arrangement of the slides 44 and 45 may be omitted, because both working operations are then carried out by the work-piece.

Figs. 7, 8, and 9 show such a vertical shaping-machine in which only the tool rotates and the table 47 receives only the movements necessary for the reproduction of profiles. The stepped pulley 50, arranged on the drivingaxle, causes, with the assistance of the bevelgearing 51 52, the rotation of the grooved shaping-spindle 53, which is adjustable by a sleeve 54 and carries at its lower end the shaping-tool 55. By means of a worm 56 the axle of the stepped pulley 50 rotates alsoa wormwheel 57, wedged to a vertical axle 58, revolving a grooved axle 6l by means of wormwheels 59 and 60. This rotation is transmitted by a worm and worm-wheel in the casing 64 to an axle 65, which after the uncoupling of the worm-wheel may also be rotated by hand. ln the same manner and by the same mechanism as in Figs.l3 and 4 a work-table 63 and a slide 24, Figs. 3 and 4, receive in this machine a sinuous movement, a slide 62 being only moved in one direction in the same manner as the slide 23, Figs. 3 and 4. In this machine the templet4 is rigidly connected with the frame of the machine, on the rails of which the slide 62 slides in the same manner as the slide 23 on the guides of the base-plate 29.

The construction shown by Fig. 10 differs from Figs. 7 to 9 in that the templet4 is connected to the slide 63 and the bearing for the axle 1 is provided integrally with the lower part 105 of the frame ofl the machine. The lower end of axle 1 carries a bevel-wheel 104, which is in engagement with another bevelwheel 103. The shaft to which wheel 103 is connected carries another bevel-wheel 102, being in engagement with a wheel 101. This latter wheel and a driving worm-wheel 60 are secured to a shaft 61. The bearings for these shafts are provided in the lower part 105 of the frame of the machine.
